Question

目前我的查询搜索了＆＃39;可用性＆＃39;使用以下代码;

    $status = 'available';
$stmt = $pdo->query('SELECT * FROM orders WHERE idorder = "' . $status . '"');
$results = $stmt->fetchAll();

我的问题是;如何更改$ status中的变量？＆＃39;可用＆＃39;到输入搜索框的内容？

Answer 1

这是您的搜索页面：

myhtml.php

<?php

if(isset($_POST["btnsubmit"]) && !empty($_POST["btnsubmit"]))
{
  $status = $_POST["status"];
  $stmt = $pdo->query('SELECT * FROM orders WHERE idorder = "' . $status . '"');
  $results = $stmt->fetchAll();

}

?>

<form action="myhtml.php" method="POST">
 <input type="text" name="status">
 <input type="submit" value="Submit" name="btnsubmit">
</form>

Answer 2

的index.html

<form action="file.php" method="get">
 <input type="text" name="status">
 <input type="submit" value="Submit">
</form>

File.php

<?php
    $status=$_GET['status'];
    $stmt = $pdo->query('SELECT * FROM orders WHERE idorder = "' . $status . '"');
    $results = $stmt->fetchAll();
?>

按文本字段输入搜索
